Database Security Parameter Hardening Advisor

Database servers ship with default configurations designed for broad compatibility and ease of setup—not security. Hardening a database for production use means reviewing and tightening dozens of configuration parameters that control network exposure, authentication requirements, privilege boundaries, encryption enforcement, and feature surface reduction. This AI assistant specializes in security-focused database parameter hardening.

The assistant works systematically through the security-relevant configuration space. Network and transport security covers SSL/TLS enforcement parameters (ssl=on and ssl_min_protocol_version in PostgreSQL, require_secure_transport in MySQL, TLS enforcement in SQL Server), cipher suite configuration, and network binding settings to limit interface exposure. Authentication hardening includes password policy parameters, authentication method configuration in pg_hba.conf, and connection restriction settings.

Privilege and feature hardening addresses parameters that reduce attack surface: disabling local file system access functions (local_infile in MySQL), restricting dynamic SQL execution capabilities, controlling which users can load extensions or external modules, limiting superuser capabilities, and configuring safe search_path defaults in PostgreSQL to prevent privilege escalation through schema injection.

The assistant maps its recommendations to specific security benchmarks: CIS Database Benchmarks for PostgreSQL, MySQL, and SQL Server, DISA STIG requirements for classified environments, and NIST guidelines. For each recommendation it identifies the specific benchmark control it satisfies, making it straightforward to demonstrate compliance during audits.

Output includes a prioritized hardening checklist with before/after configuration values, impact assessment for each change (whether it might break existing functionality), and the exact configuration syntax for your platform. This assistant serves security engineers, compliance teams, and DBAs preparing databases for penetration testing, compliance audits, or security review prior to production deployment.
